Be it known that'l, GLEN G. GnrswoLD, a citizen of the United States,residing at' Madison, in the county of Lake and State of Ohio, d usefulImplrcvements in Manure-Spreaders; and I do l eclare that the followingis a full, clear, and l exact description oi the invention, which will l-enable others skilled in the art towhich it appertains to make and usethe same.-

My invention relates to manure spreaders, and the invention consists ina distributin v attachment adapted to be connected witg and tosupplement the work of any and all wagon body, and adapted to throw theInanure to the rear in a more or less comminuted and uniform spread,limited at the bestto about' the widthor` the wagon tread, while othersdeliver through spouts "in rows an others may even differentiate fromthese operations within narrow limits. Myn invention on' the contrary isa broad-casting Idevice auxiliary to the revolving spreader lin commonuse and receiving the manure therefrom through a delivery sout C. Saiddevice consists of a refcra ly concavo-convex disk D of suitabieproportions supported in a nearly horizontal position at the bottom ofspout C by me -ns o a iixed bearing sleeve E rigid with cross bar F ofthe wagon frame and a shaft G through said sleeve havin(y said spreadermounted on its lower exposed end. A variable speed gear H of diskpattern with concentricteeth on its top surface is fixed on G an'd `smeshed by least all that have come to my knowled e.

l Hitherto the mainiault or objection ound i in mechanical spreaders ofmanure has been thev narrowness oi'l their throw, none with familiarbeing able to cover more than three kand a haii or Jr'our and a halffeet of width and necessitating the traversing of a field backend forthso often and in such close relation that the mere distribution of themasumed a great amount oi time. lThis was and is objectionable arl-ticularly in plowed fields where the .dra t is heavy and much haulingun uly packs the inion J rom oneof the wheels of the wagon through anysuitable power connections or. from any available source oi power aboutthe wagon. Said pinion is adjustabl fixed on shaft so as to mesh thesame wit any one oi' the several series of teeth on gear H according tothe speed of rotation desired for the spreader, and such s eed will besub'ect to various conditions as ereinbei'ore in icated and as must beobvious. In any event, however, tl 's' eed must be rapid to cover a widepath of retribution and which will also thin the quantity left u on theground, and said adjustment ador s allthe ran e of speed from slow' tofast that the prear er may require, es ecially when consi ered inconunction th the travel of the team. 1e sai a reader has radial vanesor blades d upon both sides, and tlc'spout C is arran Yed to deliver themanure directly upon tie center thereof as nearly as can be to promoteevenness of work. A centrifugal action being imparted by the spreader 1twill throw the manure evenly in a complete circle a distance or" as manyfeet from the center as may be derom five feet up toten and even thispoint, and successfully overcomes .and remedies' these ob'ections andthe limitations of the sprea ers commonly in use by taking the manuretherefrom at about the place oi its discharge and a pl ing a principleoi spreading thereto w 'c will easilyA and evenly compass a path oi fromtwelve to Jforty feet across7 the width of distribution more or lessdeending on sundry rynes or moisture of the manure, its iineness orcoarseness an its li htness or heaviness. Then again the s ee oi thedistributing attachment enters into the calculation asa factor,according to accoildirig as a light or heavy spread be wanted.. 1 l

' .Having these objects .and operations in view, Figure 1 oi thedrawings represents a side 'elevation of a-Wagon equipped with an t dayspreader and my invention operatively related thereto, and Fig. 2is alan vewof-mys reader'prcper. *i

3 is a on itudinal sectional elevation ci the wagon an parte shown inFig. 1, and Fig; 4 l aired, say

transversely of the rear end of the wagon, or.

on shaft L, which is power driven twenty. The mouth of deliveryl spoutor hood C is as wide at the top as distributor or beater B, and anyavailable means may be radial spreader itself with means to supportemployed to convey the manure in the wagon to the beater or distributer.The spreader being concave-convex with blades or ribs on both sides itcan be reversed according tothe work to be done. bviously, for ya widethrow and fine distribution the convex side will be up, but for heavymanure and atleast for some varieties of fertilizers the concave sidewill be on top. v

By reason of spreading. in a circle as the wagon moves along, the groundis practically some measure to lining the manure, both as it is droppedthereon and as it is cast off with greater or less velocity.

lf desired the entire spreading attachl ment comprised in my inventionmay be re -moved and the revolving distributor or beater B will do itswork alone as formerly. My invention therefor' is in itself a completeand independent attachment designed to be sold in the market as such andto be used with the various makes of manure distribu-- ters now quitegenerally in use.

The spreader is shown as set at a slightly load introduced on thisaccount is comparatively small and bears no proportion to the very'greatadvantage derived from its superior work. l I Practically the inventionconsists in the and .couple it up in operating position, and ultimatelyin its combination with the dis- 1 tributer.

The vanespblades or ribs d are placed on both sides of the spreader whenit is designed .to be reversible, and they may have any desirableelevation and shape, so that they will remote the spreading of themanure or ertilizer. The spreader also may be made interchangeable sothat as to use larger or smaller ones according to the material .to bespread.

What l claim is:

l. A. disk for a manure spreader having radial vanes on both sides' andadapted to be reversed.

:2. A reversible disk` for a manure spreader concavo-convex in crosssection and provided withradial vanes on both. sides, whereby a long orshort throw can be give-n the manure.

3. A manure spreader of disk shape anda shaft supporting the same in asubstantially horizontal position, in combination with a toothedrevolving distributer on a plane above said spreader and a chute forconvey GLEN G. GRISVVOLD.
